DI Optical’s compact FC1 parallax free prism gun-sight weights just 4.2 oz. and offers full features in a lightweight package. The retangular 17mm x 23mm lens with a proprietary multi-layer anti-reflective coating provides an exceptionally well defined red dot without ghost image, flare, reflection, or blurriness.
Housed in a rugged case CNC machined from a solid block of 6061-T6 aircraft grade aluminum, the FC1 is unsurpassed in rugged construction. The single, easy to use push button selects between 7 daytime and 7 night vision compatible modes. The FC1 mounts on standard a MIL-STD 1913 rail, or it can be used with an optional lever operated quick disconnect mount.
